Best Builder Hall Level 10 Trophy/Defense Base Layouts for COC Clash of Clans

Builder Hall 10 (BH10) is the current zenith of the Builder Base, representing the highest level of strategic gameplay. It introduces a powerful new troop with a unique mode-switching ability and unlocks the final major defensive structure, pushing players to master complex, multi-layered strategies. The upgrade costs 4,800,000 Builder Gold and takes 5 days to complete. The Builder Hall itself achieves a magnificent final form, adorned with deep blue crystals and intricate, glowing technological patterns.

Key Unlocks: A Second X-Bow and New Traps

BH10 focuses on refining and strengthening your existing defensive capabilities to counter the most powerful armies in the game.

• X-Bow (x1): The most significant defensive addition at BH10 is the ability to build a second X-Bow. Having two of these rapid-firing defenses allows for immense and flexible single-target damage, creating a formidable defensive core against both ground and air Heroes.
• Additional Mine & Mega Mine (x1 each): You get one more of each type of mine, adding extra layers of trap-based defense to surprise attackers and weaken high-hitpoint troops.
• Additional Walls (x10 segments): The final set of wall pieces allows you to fully enclose your base, protect your two X-Bows, and perfect the defensive flow across both stages of your village.

New Offensive Potential: The Dual-Mode Wizard

Your offensive arsenal is completed with a highly versatile and strategic troop that can adapt to any situation on the fly.

• Electrofire Wizard: Unlocked by upgrading the Builder Barracks to level 10, the Electrofire Wizard is a masterful troop who can switch between two attack modes.
• Inferno Mode (Fire): He shoots a single, focused beam of fire that builds up damage over time, identical to a single-target Inferno Tower. This mode is perfect for melting high-health targets like Heroes, Crushers, or a Super P.E.K.K.A.
• Electro-Shock Mode (Electric): He shoots a chain lightning attack that can bounce to multiple targets, similar to an Electro Dragon. This mode is ideal for clearing out low-health support troops or swarms like Bats or Skeletons. His special ability, Mode Switch, allows you to toggle between these two attack forms once per deployment, offering incredible tactical flexibility during an attack.

Strategic Implications

Builder Hall 10 is the ultimate sandbox of Builder Base strategy, defined by choice and adaptability.

• On Offense: The Electrofire Wizard is a high-skill-cap troop. Mastering when to use his Mode Switch ability is crucial. You might start in Inferno Mode to burn down a key defense like the Roaster, then switch to Electro-Shock Mode to clear out the Guard Post troops that emerge. With six army camps and two maxed-out Heroes, offensive power is at its absolute peak, allowing for complex, multi-stage attacks that require flawless execution.
• On Defense: The addition of a second X-Bow creates a defensive core with unparalleled single-target damage. A common strategy is to set one X-Bow to 'Ground' and the other to 'Air', creating a balanced defense that is difficult for an attacker to exploit with just one army composition. Base building becomes an art form, focused on protecting your two X-Bows and two Mega Teslas while using your area-damage defenses like the Lava Launcher and Roaster to funnel troops into your kill zones. Defending successfully at BH10 requires anticipating the most powerful attack strategies and creating a layout with no obvious weaknesses.
